POR-15 High Temp Heat Resistant Paint

POR-15 High Temp Heat-Resistant Paint is capable of withstanding extreme temperatures up to 1200°F / 648.8°C and will resist cracking, chipping, and peeling. This high temperature coating is also extremely weather, salt, and moisture resistant when applied in two or three thin coats and cured at low baking temperatures. This is a direct to cleaned prepped metal coating. No primer or top coat necessary. Our heat resistant paint is UV resistant and is the most uniform heat-resistant coating available anywhere and will maintain rich, brilliant colors without burning off or discoloring. POR-15 High Temp can be applied to manifolds, headers, exhaust pipes, barbecues, cars, machinery, or any metal surface that encounters extreme heat. POR-15 high-heat coating meets or exceeds properties and requirements of MIL-C-13370.

Note: To reduce POR-15 High Temp paint when spraying with an HLVP system, use POR-15 Reducer Solvent. You can reduce up to 10% maximum. You can also use POR-15 Reducer Solvent for cleanup.

Replaces POR-20, Black Velvet, Fire Seal 2000, and Factory Manifold Gray

High Temp

Nice coating

Great for exhaust touch up

Robert Rapalus
POR-15 Manifold Paint

Sandblasted my cast iron exhaust manifold and applied two costs as per directions. Placed manifold in a powder coat oven the following day at 400 degrees to cure. Looks great! Have enough left for a set of V-8 manifolds.

Janet Carpenter
Great product!

Used on my Fisher woodstove I’m refurbishing. So far it’s holding up and looks great!

I am using the POR-15 High Temp on a 1949 MG YT I am restoring. Thus far it works and looks great on the manifold.

Read all safety warnings and precautions on label before use.


Liquid paint directions:

On previously painted surfaces blistered and loose paint must be removed. Sandblasting is the optimum surface preparation. Clean painted and bare metal surfaces with POR-15 Cleaner Degreaser to ensure that the surface is clean, dry, and free from oil, grease, dirt, salts, and any other contaminants. Paint  all bare areas with two coats of POR-15 High Temp Coating. Glossy surfaces should be roughened with 320 grit sand paper before recoating. Allow POR-15 High Temp Coating to cure for 24 hours on the surface before temperature is raised above 300°F for full cure.

Dry time: Cures to touch in 4 hours. Second coat can be applied in 24 hours, depending on ambient temperature and humidity. POR-15 High Temp reaches maximum hardness after heat exposure above 300°F (150°C) for 15 minutes and then allowed to cool down.

Clean up: Do not put left-over paint back into can. Clean all equipment immediately after use. At the same time, flush out all fluid lines and carefully clean pressure pots. Use clean POR-15 Solvent only. It is also good practice to periodically clean the spray tip or the fluid tip/air cap combination during the course of the working day or shift.

Aerosol spray directions:

Surface must be clean, dry an free of all oil and other contaminants before painting. Sandblasting is the optimum surface preparation. Protect surrounding areas from spray mist. Must be heat cured at a minimum temperature of 400°F (205°C) for two hours. More than one coat may be required for full hide.

  • Shake can at least one minute before and occasionally during use.
  • Spray surface with steady, even strokes at a distance of 8 to 10 inches. Several light coats give a better finish than one heavy coat. For best results, recoat within 1 hour or after 24.

Cleanup: To prevent clogs in spray nozzle, hold can upside down and spray until clear gas appears. Completely empty cans may be recycled or disposed of with regular trash. Dispose of partially empty cans responsibly. DO NOT puncture, incinerate or compact.
